During the monitoring period, winter wheat in Germany was in the overwintering stage. CropWatch agri-climatic indicators show that national average cumulative precipitation was 129 mm, 37% below the 15-year average; the temperature was 2.7°C (1.0°C lower than the 15-year average); and photosynthetically active radiation was 11% higher than the 15-year average, but under cold and dry conditions it was difficult for this increase to be effectively converted into biomass growth. Under the combined influence of these factors, potential biomass was 12% lower than normal.
CropWatch monitoring shows that the cropped arable land fraction was 97%, slightly lower than the past five-year average (−2%), indicating that most cropland still maintained crop/cover-crop cover during winter, though the coverage rate declined slightly relative to recent norms. The national peak vegetation index was 0.77, suggesting that relatively good peak greenness periods still occurred within the monitoring window, but overall signals of production potential were weak.
Overall, this monitoring period coincided with the overwintering stage. Conditions nationwide were drier and colder than normal, and NDVI remained at a low level with little change, mainly because crops had entered dormancy and growth had slowed; this does not imply insufficient soil moisture. If precipitation remains below normal, soil moisture deficits may occur at spring green-up, leading to a slower recovery of crop growth and thereby affecting later development and yield formation of winter wheat.
